David Hugh "Darby" Munro (5 March 1913 – 3 April 1966) also known as "the Demon" or the "Brown Bomber" was an Aboriginal Australian jockey born in Caulfield.

This same article asserts that Darby got his jockey's ticket as his father's apprentice, but his first race was on Carey's Karuma in a Tattersall's Two-year-old Handicap on 21 May 1927, and was beaten by a horse named Rosso.

[4] Munro came into prominence in May 1927 when he won the Prospect Handicap on Release, beating his famous brother Jim on Quixotic.

His services were soon in demand by such famous trainers as Jackson "Jack" Holt "the Wizard of Mordialloc" (c. 1880–1951), Bailey Payten (c. 1896 – 9 September 1948),[5] and Peter Riddle (c. 1885 – 29 June 1947).

[7] Unlike many other outstanding jockeys, he was not interested in golf, but kept himself fit by riding and swimming, an exercise he enjoyed, and never dieted to keep his weight down, though he did have a problem later on.

[8] He was renowned for his stony poker face, which may have contributed to the ambivalent attitude of the public towards him: cheering his wins and booing his failures.
